George Nesterczuk, President Trump’s nominee to lead the Office of Personnel Management, has requested withdrawal of his nomination for the position in an effort to not cause further delays for the administration in getting the position filled.

He stated in a letter to President Trump that “partisan attacks” against him threaten to delay filling the position, and while he believes they have no merit, he wishes to withdraw from consideration of the position in the hopes that he will not “be the cause of additional delay in the selection of of a new Director of OPM.”

The White House confirmed the withdrawal of the nomination on Wednesday when it published notice of Nesterczuk’s withdrawal sent to the Senate:

George Nesterczuk, of Virginia, to be Director of the Office of Personnel Management for a term of four years, vice Katherine Archuleta, resigned, which was sent to the Senate on May 25, 2017

Nesterczuk is the president of Nesterczuk and Associates. The Virginia based company provides management consulting services.
